1. In Fig. 25-35, the battery has potential difference V= 9.0 V, C2 = 3.0 \if, C4 = 6.0 |aF, and all the
capacitors are initially uncharged. When switch S is closed, a total charge of 12 |aC passes through point
o and a total charge of 9.0 |_iC passes through point b.

2. In Fig. 25-28, a potential difference V = 100 V is applied across a capacitor arrangement with
capacitances Ci - 10.0 uF, C2 = 6.00 |aF, and C3 = 15.0 uF. Find the following values.

3. In Fig. 25-41, how much charge is stored on the parallel plate capacitors by the 12.0 V battery? One is
filled with air, and the other is filled with a dielectric for which K = 2.65; both have a plate area of 4.65
xlO"3 m2 and a plate separation of 2.00 mm.
